Use of Excel Spreadsheets to Calculate Forced

2021-3-5 · Obtaining a good estimate for a forced convection heat transfer coefficient is the major part of most calculations. The downloadable Excel spreadsheets included with this article will help you estimate the heat transfer coefficients. We use Reynolds/ Prandtl/ Nusselt number correlations to calculate the Nusselt number for the particular configuration, and then to calculate the coefficient.
